Vim li cas luam tawm Circuit Board xav tau kev tswj impedance?

Hauv cov kab hluav taws xob xaim hluav taws xob ntawm cov khoom siv hluav taws xob, qhov kev tiv thaiv tau ntsib thaum lub teeb liab siab lossis hluav taws xob yoj propagates hu ua impedance.Vim li cas PCB boards yuav tsum tau impedance thaum lub sij hawm tsim cov txheej txheem ntawm Circuit Court board Hoobkas?Cia peb txheeb xyuas los ntawm 4 yam hauv qab no:

1. Cov PCB Circuit Board ntawm lub Circuit Court board Hoobkas yuav tsum xav txog plugging thiab txhim kho cov khoom siv hluav taws xob, thiab tom qab SMT thaj kev sib txuas kuj yuav tsum xav txog cov teeb meem xws li conductivity thiab teeb liab kis tau tus mob, yog li qhov qis impedance, qhov zoo dua.

3. Lub tin plating ntawm pcb Circuit Court boards yog feem ntau muaj teeb meem nyob rau hauv cov khoom ntawm tag nrho cov Circuit Court board, thiab nws yog qhov tseem ceeb txuas uas cuam tshuam rau impedance;Nws qhov loj tshaj qhov tsis xws luag yog yooj yim oxidation los yog deliquescence, tsis zoo solderability, ua rau lub Circuit Court board nyuaj rau solder thiab dhau impedance.Siab, ua rau tsis zoo conductivity los yog instability ntawm tag nrho cov board kev ua tau zoo.

4. Cov conductors nyob rau hauv lub PCB Circuit Court board ntawm lub Circuit Court board Hoobkas yuav kis tau ntau yam teeb liab.Lub Circuit Court nws tus kheej yuav hloov qhov impedance tus nqi vim yog etching, pawg tuab, hlau dav thiab lwm yam, uas yuav ua rau lub teeb liab distortion thiab ua rau lub Circuit Court board.Kev ua tau zoo poob qis, yog li koj yuav tsum tswj hwm tus nqi impedance nyob rau hauv ib qho chaw
